Concentration of solutions


  • Many chemical reactions take place in solutions. The concentration of a solution can be measured in mass per given volume of solution, eg grams per dm3 (g/dm3).
  • Students should be able to:
  • calculate the mass of solute in a given volume of solution of known concentration in terms of mass per given volume of solution
  • (HT only) explain how the mass of a solute and the volume of a solution is related to the concentration of the solution.
